Detailed Description

The present utility model will be further described in detail with reference to examples so as to enable those skilled in the art to more clearly understand and understand the present utility model. It should be understood that the following specific embodiments are only for explaining the present utility model, and it is convenient to understand that the technical solutions provided by the present utility model are not limited to the technical solutions provided by the following embodiments, and the technical solutions provided by the embodiments should not limit the protection scope of the present utility model.

Examples

As shown in fig. 1 and 2, the present embodiment provides a clamping forceps for orthopedic surgery, which includes a forceps head, a first connecting piece, a second connecting piece, a pin shaft, a first handle and a second handle, wherein concave-convex stripes are provided on the inner side of the forceps head to increase the friction force of clamping, the first connecting piece and the first handle are in an integral structure, the second connecting piece and the second handle are in an integral structure, the first handle and the second handle are in rotational connection through the pin shaft, and anti-slip stripes are further provided on the outer sides of the first handle and the second handle for holding and preventing slipping.

The embodiment realizes the fixation of the clamping jaw opening through the movable limiting rod, the upper accessory thereof, the fixed limiting rod and the upper accessory thereof, specifically speaking, the lower end of the inner side of the first handle is provided with the movable limiting rod which is rotationally connected with the movable limiting rod, the right side of the upper end of the movable limiting rod is provided with a plurality of female positioning teeth, the lower end of the movable limiting rod is provided with an operating rod, the lower end of the inner side of the second handle is provided with the fixed limiting rod which is fixedly connected with the movable limiting rod, and the lower end of the fixed limiting rod is provided with a plurality of male positioning teeth which are matched with the female positioning teeth; wherein, the lower end of the inner side of the first handle is provided with a connecting part, and the left end of the movable limiting rod is rotationally connected with the connecting part; the operation rod and the movable limiting rod are of an integrated structure, and the operation rod is protruded to the left end to be bent for the convenience of operation; through the arrangement, the clamping connection of the movable limiting rod and the fixed limiting rod is realized through the movable limiting rod, the female positioning teeth on the movable limiting rod and the fixed limiting rod and the male positioning teeth on the fixed limiting rod, and therefore the opening degree of the clamping pliers is fixed.

In this embodiment, female positioning teeth and public positioning teeth all slope and two inclination symmetry, and the quantity of female positioning teeth and public positioning teeth sets up as follows: the number of the female positioning teeth is 3-5, and the number of the male positioning teeth is 3-4 times of that of the female positioning teeth along the fixed limiting rod.

In order to ensure that the movable limiting rod and the fixed limiting rod can be smoothly clamped through the female positioning teeth and the male positioning teeth, the movable limiting rod is positioned below the fixed limiting rod in the vertical direction (vertical direction).

In order to prevent the movable limiting rod from falling off after the movable limiting rod and the fixed limiting rod are clamped and fixed through the female positioning teeth and the male positioning teeth, a jacking spring is arranged between the operating rod and the inner side of the first handle, the right end of the jacking spring is inclined upwards, the inclination angle of the jacking spring is 5-10 degrees, the jacking spring is used for upwards jacking the movable limiting rod under the action of the restoring force of the jacking spring, and the movable limiting rod is prevented from falling off from the vertical relatively fixed limiting rod.

Based on the above structure, the working principle of the utility model is as follows: when the clamping pliers are operated to clamp an object to be clamped, the first handle and the second handle of the clamping pliers are held by hands, then the operating rod is pressed down by hands, the operating rod overcomes the elasticity of the ejection spring and drives the movable limiting rod to rotate downwards, and at the moment, the movable limiting rod is separated from the fixed limiting rod, so that the clamping pliers are normally used; after the clamping pliers clamp the object to be clamped, the operating rod is loosened, the operating rod returns under the action of the jacking spring and drives the movable limiting rod to rotate upwards, the female positioning teeth on the movable limiting rod are clamped into the male positioning teeth on the fixed limiting rod, the female positioning teeth and the male positioning teeth form a tooth staggered structure, the jacking spring props against the movable limiting rod, at the moment, the movable limiting rod and the fixed limiting rod are clamped and fixed, thereby fixing the opening degree of the clamping pliers, the object to be clamped is clamped by the jaws, at the moment, the handle of the clamping pliers is not required to be held with force again, after the object to be clamped is taken out, the operating rod is pressed down, the movable limiting rod can be separated from the fixed limiting rod, and the jaws are opened.

The foregoing is a preferred embodiment of the present utility model. It should be noted that those skilled in the art may make several modifications without departing from the design principles and technical solutions of the present utility model, and these modifications should also be considered as the protection scope of the present utility model.
